Today I ran my still-under-revision Ruby Mountain dungeon for my players. It now has Thulid in it, and I looked in the Field Guide to refresh my memory on the details of their spawning.

The details weren't there. Now, this is a monster I created, so I knew the rules existed. Where were they?

A bit of searching led me to the original release of the Thulid, in R2 of the Almanack. The material there runs across two pages; what's in the Field Guide is just the material from the first page.

Gah.

So since the Almanack was recalled and the Field Guide took its place, the Thulids have been missing a big, important piece.

I'll be uploading a new Field Guide release in about two weeks (no point giving away any secrets to my players before next session). IN the meantime, if there was a reason we omitted this material, someone might refresh my memory...

Weird. Actually the Field Guide pulled the entry from the old Monster Supplement, not the old Almanac itself, so I am unsure where the omission would have come from. But if there was an omission otherwise, it would have been my fault... and unintentional.

While running CS1 Castle by the Sea: Castle of the Unknown today, I noticed that the saves for the Giant Screaming Tarantula are written out wrong:

save vs. poison

instead of the correct

save vs. Poison

No idea how many other monsters are wrong this way.

Also, the Jack O'Lantern is maybe a bit tough. AC 17 and an attack that basically always hits (a breath weapon with no limit to the number of times it can be used). I'm thinking maybe drop the AC to 15. Thoughts?

I'm not seeing that in the PDF, and ran a search in the ODT and didn't see it there either. But, running a search on all saves did find some inconsistencies, so I've corrected those along with reducing the JackO'Lantern AC, so will email you R29.
